nodes for the chapters, chapter-like sections, and the major

appendices. This includes the indices, so long as they are in

chapter-like sections, such as unnumbered sections.

||
* The second and subsequent parts contain a listing of the other,
|
||
lower level menus, in order. This way, an inquirer can go
|
||
directly to a particular node if he or she is searching for
|
||
specific information.

Requirements:

hierarchical level node,

"Major mode for editing Texinfo files.
|
||
|
||
It has these extra commands:
|
||
\\{texinfo-mode-map}
|
||
|
||
These are files that are used as input for TeX to make printed manuals
|
||
and also to be turned into Info files with \\[makeinfo-buffer] or
|
||
the `makeinfo' program. These files must be written in a very restricted and
|
||
modified version of TeX input format.
|
||
|
||
Editing commands are like text-mode except that the syntax table is
|
||
set up so expression commands skip Texinfo bracket groups. To see
|
||
what the Info version of a region of the Texinfo file will look like,
|
||
use \\[makeinfo-region], which runs `makeinfo' on the current region.
|
||
|
||
You can show the structure of a Texinfo file with \\[texinfo-show-structure].
|
||
This command shows the structure of a Texinfo file by listing the
|
||
lines with the @-sign commands for @chapter, @section, and the like.
|
||
These lines are displayed in another window called the *Occur* window.
|
||
In that window, you can position the cursor over one of the lines and
|
||
use \\[occur-mode-goto-occurrence], to jump to the corresponding spot
|
||
in the Texinfo file.
|
||
|
||
In addition, Texinfo mode provides commands that insert various
|
||
frequently used @-sign commands into the buffer. You can use these
|
||
commands to save keystrokes. And you can insert balanced braces with
|
||
\\[texinfo-insert-braces] and later use the command \\[up-list] to
|
||
move forward past the closing brace.
|
||
|
||
Also, Texinfo mode provides functions for automatically creating or
|
||
updating menus and node pointers. These functions
|
||
|
||
* insert the `Next', `Previous' and `Up' pointers of a node,
|
||
* insert or update the menu for a section, and
|
||
* create a master menu for a Texinfo source file.
|
||
|
||
Here are the functions:
|
||
|
||
texinfo-update-node \\[texinfo-update-node]
|
||
texinfo-every-node-update \\[texinfo-every-node-update]
|
||
texinfo-sequential-node-update
|
||
|
||
texinfo-make-menu \\[texinfo-make-menu]
|
||
texinfo-all-menus-update \\[texinfo-all-menus-update]
|
||
texinfo-master-menu
|
||
|
||
texinfo-indent-menu-description (column &optional region-p)
|
||
|
||
The `texinfo-column-for-description' variable specifies the column to
|
||
which menu descriptions are indented.
|
||
|
||
Passed an argument (a prefix argument, if interactive), the
|
||
`texinfo-update-node' and `texinfo-make-menu' functions do their jobs
|
||
in the region.
|
||
|
||
To use the updating commands, you must structure your Texinfo file
|
||
hierarchically, such that each `@node' line, with the exception of the
|
||
Top node, is accompanied by some kind of section line, such as an
|
||
`@chapter' or `@section' line.
|
||
|
||
If the file has a `top' node, it must be called `top' or `Top' and
|
||
be the first node in the file.
|
||
|
||
Entering Texinfo mode calls the value of `text-mode-hook', and then the
|
||
value of `texinfo-mode-hook'."
